Small, compact yet simple 50cc, designed as a modular kids first bike.

After many years of feedback on our best selling kids bike, we have made a few well overdue changes. The TSK50 has received a revamp on all levels which allow an awesome little package for junior riders to become even better.


Firstly, we have applied our new mini stealth plastics which give the bike a slick look that appeals to kids and adults alike, it now matches the rest of our bikes in the lineup. We thought the power on our old bikes was sufficient, here at Thumpstar, we are always looking for that extra thump. The TSK50 has a completely new engine, which is semi automatic rather than fully automatic, has both an electric and kick start, and overall provides more power, allowing heavier junior riders. Safety on a kids bike is a must have feature, an emergency lanyard which kills the bike should your child come off, coupled with an adjustable throttle limiter, provides full parental control of the bike.


A great first bike that grows with your young rider, designed to be upgradeable to pro-long service life as your child grows, simply upgrade the forks and rear suspension to the taller option. (optional taller suspensions package available early 2020)
